NeuroArm possesses the dexterity to perform microsurgery, outside of the MRI system.
Telerobotic operations[4] both inside and outside the magnet are performed using specialized tool sets based on standard neurosurgical instruments, adapted to the end effectors. Using these, neuroArm is able to cut and manipulate soft tissue, dissect tissue planes, suture, biopsy, electrocauterize, aspirate and irrigate. NeuroArm is 3 feet (0.91 m) tall and 2 feet (0.61 m) wide, but it can be adjusted to fit any table height. The robot weighs 500 pounds and has two ambidextrous arms. It sits on castors and can be easily rolled in and out of position. It has a fail-safe braking mechanism that secures it to the floor preventing any movement.

neuroArm is the world’s first MRI-compatible surgical robot capable of both microsurgery and image guided biopsy. The surgical robotic system is controlled by a surgeon from a computer workstation, working in conjunction with intraoperative MR (magnetic resonance) imaging. Dr. Sutherland developed the intraoperative MRI machine with Winnipeg-based IMRIS Inc. The technology allows a high field MRI scanner to move in to the operating room on demand, providing imaging during the surgical procedure without compromising patient safety

What fun!
I can just see little robots running around some day 
doing all our work for us
